rules/imp/generate/index.js

Developer reference: this page includes exported implementation details. BUILD authors should prefer the User API reference.

planGeneratedOutputs()

planGeneratedOutputs(api, { tools, inputs, outputPaths, argv })

Validate the authoring surface that generatedFiles() and //rules/imp/codegen's codegen() have in common, and name one action output slot per output path. The two differ only in where their outputs go — the workspace, or the graph — so they share one set of rules about what a caller may declare. Internal to the two generator entrypoints; not part of the public rule API.

Returns: {toolNames: string[], inputNames: string[], slots: string[]}

generatedFileIsStale()

generatedFileIsStale(path, digest)

Report whether the generated content at digest differs from the file currently at path in the workspace. A missing file counts as stale.

Returns: boolean
